“United as One” is the 7th and final book of the “I am Number Four” series by James Frey. This action-packed series ends in a breathtaking and satisfying conclusion which takes place in a dystopian society where the “Mogadorians,” who is led by Setrakus Ra, try to take over earth to get it’s resources. The main characters of this book all have unique numbers which symbolize what order they will die in, but the charm was destroyed. This book shows the final battles of the war, and how earth would react to a planet invasion. All the fights and events that happen in the book leaves you wanting to read more and I found myself hooked for the entire book series. There is some foul language and deaths in the book, and I recommend that you at least read the books before this one to prevent any confusion. Will they be able to win the war on their own or will they realize that power in numbers will save all?
